9 This invention which relates to a new or improved mechanical pipe scraper has in view the provision of a mechanically operated device for cleaning a fouled pipe.

Broadly, the invention consists of a suitable mechanical gearing with means to operand cutting out ate same by hand or by power, the gearing machine power.

being adapted to drive a reamer or other cutting or scouringtool, over which latter the bowl of the pipe isheld.

1n a'pre'ferred form of construction, a boxlike structure or casing is clamped by suitable means to a fixture, such as the edge of a table, and houses a pair ofshafts or spindles carrying inter-acting gear wheels, so that.

rotation of one shaft causes the other to revolve at a suitable cutting speed. The operated spindle may be driven by hand or The two spindles above referred to are preferably but not essentially at right angles to each other, the driving spindle being arranged horizontally and the driven spindle, carrying the cutting tool,

vertical. The reamer or other tool, may be detachable and other interchangeable tools provided.

In order that the invention may be more readily understood reference is dlrected to the accompanying sheet of drawings wl1ere- Figure 1 is a vertical sectional elevation of a mechanically operated pipe cleaner in accordance with my invention. 1

Figure 2 is a plan view of the device with the tool, refuse tray and cover plate removed.

Figure 3 is a pictorial View of a detache ainctrically opposite slots 6 in the end of the spindle f. A helical gear wheel 7 affixed to the vertical spindle meshes with a corresponding helical gear wheel 8 afiixed to a horizontal spindle. 9, the end of which latter passes through the side of the casing 10 and carries a suitable handle ll on its exterior end. Bearing brackets 12 are pro- 'vided. Positioned at each interior corner of the casing 10 is a cylindrical pillar 18, to

soldered or otherwise secured. A cover plate screws15 which engage with screwed holes 16 in the cornerpillars 13. A tray 17- to collect the refuse which falls from the pipe being cleaned and to hold Jother cutters pendinguse rests upon the cover plate. The refuse tray 17 has a vertically disposed sleeve 18 which servesas a guide for the vertical spindle 4. To'prevent the refuse tray from I swinging about this sleeve '18 as a pivot .a 7

small downwardly extending projection or snug 19, passes through a hole in the floor of the refuse tray and engages within a recess or blind hole 20 in the upper surface of the cover plate 14. A substantially U-shaped member 91 otherwisesecured to the floor of-the casing screwed, riveted or '10, carries a thumb-screw 22 or the eq uivalent device, by means of which the casing 10 1s clamped to any suitable fixture 23, 'such as a table, mantelpiece or counter. V

Figure 3'illustrates a finishing tool comprising a plurality of more or less resilient blades 24, the outer edges of which are sharpened, so that without unduly cutting the bowl of the pipe, the'blades'24l, by reason of their resilient nature, thoroughly scrapethe interior thereof. In the tool shown, the flat cross member 5 is elongated to form fin ger bars by means of, which thetool may. be readily removed without soiling the fingers. The finger bars 25 may be conveniently and are preferably en'iployedwith all kinds of tools, such as the cutter 1, Figure 1.

They device may be plated or otherwise finished and provided with ball bearings, if desired. The shape ofthe casing and refuse tray may be round, elliptical or any other I suitable shape and in lieu of the clamping bracket described, may have aperture lugs by means of which it maybe permanently attached to a fixture.

I claim :f

1. A device of the character described comprising a main housing, adriven spindle mounted therein, high speed gearing :con-

,nected with said spindle, a tool socket formedin the end of said spindle, a tool detachably positioned in said socket, a refuse tray removably'positioned on the main housno r ing and centered about said driven spindle, extending tool positioning meanson the tool 10 and means on the bottom of said main housshank, a refuse tray reinovably positioned ing for attaching the same to a support. on the main housing and centered about said 2. YA device of the character described driven spindle, and means on the bottom of 5 comprising a main housing, a driven spinsaid main housing for attaching vthe same dle mounted therein, high speed gearing to a support. V V 6 connected With said spindle, a tool socket In testimony whereof I have afiixed my formed in the end of said spindle, a tool designature hereto this 30th day of July 1926. tachably positioned in said socket, laterally WILLIAM HOWARD WARMAN.
